WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 410,631, datedSeptember 10, 1889.

Application fil d May 6, 1889. Serial No. 309,770. (No model.)

To all whom, it may concern.-

Be it known that 1, WILLIAM W. ATTE- BERRY, a citizen of the UnitedStates, residing at Chesterfield, in the county of Macoupin and State ofIllinois, have invented a new and useful iVagon-Brake, of which thefollowing is a specification.

This invention relates to wagon-brakes; and it has for its object toconstruct a device of this class which shall possess superior advantagesin point of simplicity, durability, and efficiency.

lVith these ends in view the invention consists in the improvedconstruction and arrangement of parts which will be hereinafter fullydescribed, and particularly pointed out in the claims In the drawingshereto annexed, Figure 1 is a top view of a vehicle running-gearprovided with my improi'ed brake attachment, parts of the same havingbeen broken away for the purpose of showing the construction moreclearly. Fig. 2 is a bottom view. Fig. 3 is a longitudinal verticalsectional view. Fig. 4 is a transverse section.

The same letters refer to the same parts in all the figures.

A and B designate the front and rear axles, which are mounted in theusual manner upon wheels 0.

D designates the reach or coupling-pole, which is adjustablelongitudinally by means of a bolt E, passing through the saidcouplingpole and through a plate F, connecting the front ends of therear hounds G G.

H is the king-bolt, which connects the front bolster pivot-ally with thefront axle and the front end of the coupling-bolt. The rear end of thelatter extends through a recess in the under side of the rear bolster.

The front hounds, between the front ends of which the tongue is to bemounted, are arranged in the usual manner between the front axle andsand-board, and the rear ends of said front hounds are connected in theusual manner by means of cross-bars I and J, arranged, respectively,above and below the reach.

K designates a plate, which is bolted or otherwise firmly secured uponthe plate F and the front ends of the rear hounds G. Said plate isprovided at each end with a downwardly-extending loop or bracket L, inwhich the brake-bar M is arranged to slide longitudinally, as shown. Thesaid brake-bar is provided at each end with the brake-shoes N N, adaptedto bear against the rear wheels of the vehicle. The brake-bar M isprovided with downwardly-extending pins or studs 0 0, adapted to retainthe said brake-bar in position in the brackets L and prevent it frombeing displaced laterally.

Secured centrally to the rear side of the brake-bar M is a block P, towhich is attached a leaf-spring Q, the ends of which bear against therear sides of the loops or brackets L L, thereby serving to force thesaid brake-bar normally in a forward direction.

Mounted pivotally upon the under side of the rear axle B are two leversR R, the outer ends of which are connected with the brakebar M by meansof rods S S. The bolts T '1, upon which said levers are mounted, arec011- nected with the under sides of the rear hounds G by means ofbrace-rods U, whereby the said bolts are prevented from being displacedby the strain incident to the operation of the device.

V is a rod arranged to slide longitudinally in suitable bearings \V,attached to the reach or coupling-pole, and the rear end of said rod isprovided with an upwardly-extending flange or bracket X, having atransverse slot Y, through which extends a plate Z, which is connectedadjustably to the said rod D by means of screws or bolts to. The saidplate Z is also provided with a collar 1'), encircling the sliding rodV, and serving to connect the said plate and rod more firmly together.The rear end of the plate Z is provided with a T-head c, the ends ofwhich are connected by means of links (I d with the inner e nds of thelevers R R.

J ournaled in suitable bearings upon the front side of the axle A is arock-shaft e, the inner end of which has an arm or crank 00, which isconnected by a chain g with the front end of the longitudinally-slidin grod V.

The outer end of the rock-shaft c is pro vided with a lever f, by meansof which the brake mechanism may be operated either by the hand or footof the driver of the vehicle.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of my invention will bereadily understood.

It will be seen that by operating the rockshaft 6 by means of the leverf the sliding rod V will be moved in a forward direction, thereby,through the intermediate mechanism, moving the inner ends or arms of thelevers R in a forward direction and forcing the outer ends or arms ofsaid levers, together with the brake-bar M, which is connected to saidouter arms, in a rearward direction, and thus forcing the brake-shoes atthe ends of the brakebar M into contact with the rims of the hind wheelsof the vehicle. As soon as the pressure' upon the brake-lever f isreleased, the

pressure of the leaf-spring Q, attached to the block E upon the rearside of the brake-bar M, serves to restore the latter to its normalposition.

The construction of my improved wagonbrake is exceedingly simple, and itwill be found certain and effective in its operation.

By connecting the crank upon the rock-' shaft journaled upon the frontaxle to the operating-rod V by means of a chain, as herein described,the front axle may turn in the usual manner without interfering with thesuccessful operation of the brake mechanism. Having thus described myinvention, I

claim- 1. In a Wagon-brake, the combination, with the running-gear, of aplate mounted upon.

the front ends of therear hounds and having downwardly-extendingbrackets or hangers, the brake-bar arranged to slide longitudinally insaid brackets and having downwardly-extending guide-studs, a blocksecured centrally to the rear side of the brake-bar, a spring secured tothe rear side of said block and bearing against the rear ends of saidbrackets or hangers and to force the brake-bar normally in a forwarddirection, levers pivoted to the under side of the rear axle, rodsconnecting the outer ends or arms of said levers with the ends of thebrake-bar, a longitudinally-sliding rod mounted in bearings attached tothe reach, links connecting the rear end of said sliding rod with theinner ends of the levers, a rock-shaft mounted in bearings attached tothe front axle and having a crank at its inner end connected by thechain with the 1011- gitudinally-sliding rod, and an operating-lever atthe outer end of said rock-shaft, substantially as and for the purposeset forth.

2. In a wagon-brake, the combination of the longitudinally-slidingbrake-bar, a spring arranged to force the said brake-bar normally in aforward direction, levers pivoted to the under side of the rear axle,rods connecting the outer ends or arms of said levers With thelongitudinally-sliding brake-bar, a longitudinally-sliding rod mountedin bearings attached to the reach of the running-gear and having at itsrear end an upturned flange provided with the transverse slot, a plateextending through the said slot and having a ring encircling thelongitudinally-sliding rod, bolts connecting the said plate adjustablywith the lon gitudin ally-slidin g rod, links connecting the rear end ofsaid adjustable plate with the inner ends or arms of the brake-operatinglevers, and a rock-shaft journaled in bearings attached to the frontaxle and having an operatingdever at its outer end and provided at itsinner end with a crank connected by a chain with thelongitudinallysliding rod, substantially as herein set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

WILLIAM IV. ATTEBERRY.
